BOX-GAR DOOR.

Specification of Letters Patent. Patented July 19, 1910.

Application filed May 18, 1909. Serial N 0. 496,737.

To all whom it may concern:

Be it known that I, FRANK VANoY CAR- MAN, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in BOX- Car Doors, of which the following is a specification.

My invention relates to doors for railway box-cars.

The object of my invention is to provide a door, suitable for box-pars, adapted to be tightly seated and locked, and to be unlocked and unseated, by the operation of a single lever.

To this end, my invention consists in the novel construction, arrangement and hanging of the door, and its seating, locking and releasing means, which I shall now fully describe by reference to the accompanying drawings in which Figure l is a view from the inner side of the door, the inner wall plate of said door being removed. Fig. 2 is a view from the outer side of the door. Fig. 3 is a horizontal section, enlarged, on the line ww of Fig. 2. Fig. 1 is a sectional detail, enlarged, showing the hanging and seating of the door; its unseated position being shown in dotted lines. Fig. 5 is a sectional detail of one of the side locking bolts. Fig. 6 is a sectional detail showing the seating of the door in connection with one of the side locking bolts. Fig.7 is an enlarged detailed view of the retaining means for the lever 26.

1 is a portion of the side wall of a boxcar.

2 is an angle-flange secured to the outer surface of the car wall and bordering its door-opening all around, to form a seat for the door.

The door, as best seen in Figs. 3, 4 and 6, is composed of an outer wall plate 3, and an inner wall plate 1. The outer wall plate overlaps the border flange 2 of the dooropening, and has secured to the inner surface of its overlapping border an angle-flange 5 within which is secured a weatherpacking 6 of any suitable nature, preferably in the form of a rubber tube or hose. This packing lies between the two border flanges 2 and 5 and forms a weather tight joint when the door is pressed in to its seat. The outer wall plate 3 has also secured to its inner surface all around, an angle frame flange 7 which enters the door opening, and said flange forms a guide to receive a border flange 8 of the inner wall plate 4. The door is thusa hollow one, its cavity being crossed by strengthening cleats 9, Fig. 1, to which the inner wall plate may be suitably secured.

Secured to the wall 1 of the car is a hanger-track 10, in the form of a pipe, which has a bottom slot, through which enter the crank ends 11 of the hangers 12. To the extremities of these crank-ends, within the hanger-track 10 are pivotally secured shoes 13, (Fig. 4.) which suspend the hangers, and slide freely within the tubular track. A flashing plate 10 overlaps the top of the hanger track, to direct water away. There are two of these hangers 12. They are connected with the outer wall plate 3 of the door, by journal bearings 1 1, in which they oscillate on their axes. The lower extremity of each hanger has a crank 15 which plays in a slot 16 in the outer wall plate and enters the cavity of the door as seen best in Fig. 3,

Pivoted upon the inner surface of the upper part of the outer wall plate 3 of the door, Fig. 1, is a double bell-crank lever 17, to opposite ends of which are connected the links 18, the other ends of which are connected with the inner ends of the cranks 15 on the lower ends of the hangers 12. These links have turn-buckle nuts 19 to adjust their length. Pivoted upon the inner surface of the lower part of the outer wall plate 3 of the door, is another double bellcrank lever 20, to the opposite ends of which are connected the side-locking bolts 2]., the other ends of which are fitted to slide in guides 22 and to enter keepersockets 23, in the side walls of the dooropening, 1, 5 and 6. The two bell crank levers 17 and 20 are connected by a link 2 1. The pivoted shaft 25 of the lower bell-crank lever 20 passes through the outer wall plate 3 of the door, and has secured to its outer extremity the main operating lever 26, as seen in Fig. 2. This lever is adapted to fit down into a keeper-cleat 27, and to be locked therein by a hook 28 which passes through a hole in the top of the cleat. This hook is carried by a chain 29, and when seat and locking it.

in place is adapted to have applied to it any of thensual forms of seals or seal-locks to prevent it from being tampered with.

At 30 in Fig. 2 is indicated a hasp and staple fastening to temporarily hold the door from sliding when relieved of its locking devices. In Fig. 2 is also shown a rail 31 and slide ring 32 chained to the door, to limit the sliding movement of the door.

83 is a handle on the outer face of the lower portion of the door.

The operation is as follows :Suppose the door to be in the position shown in Fig. 2, that is closed and locked. To open it, the seal locking hook 28 is removed to free the main lever 26. This lever is then thrown upwardly, with the effect of withdrawing the side locking bolts 21, to release the lower portion of the door, and of turning the hangers 12 on their axes, so that their crank ends 11 will turn to throw the upper portion of the door outwardly to such an extent as to cause said portion of the door to fully clear the door-opening as is shown by the dotted lines in Fig. 4. Then by taking hold of the handle 38, the operator can pull outward the lower portion of the door to fully clear the door opening, and the whole door is now clear of and then he throws the main lever 26 down.

to its keeper-cleat 27, and locks it with the seal hook 28. This movement of the lever projects the side locking bolts 21 into their keeper sockets 23 with the effect of drawing that portion of the door tightly to its packed It also throws the cranked hangers 12 back again with the effect of drawing in the top portion of the door and pressing the whole door to its packed seat and looking it firmly in place.

The angle iron flange 7 on the inner face of the outer wall plate of the door, in addition to forming a frame for the door, also acts as a. buffer to take impact off the doorhangers while switching or handling the car. All the joints are weather and dust proof, and are tight enough to prevent freezing. The parts are so arranged and concealed as to prevent their being readily tampered with, and the door is thus, for all practical purposes, burglar proof.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination with a boX car having a door opening and an L-shaped angle bar bordering the said opening with one flange thereof projecting outward from the car door, a door fashioned to fit within the opening, the door having a border flange projecting beyond its edges in substantial alinement with the front surface of the door, and an inwardly projecting flange overlapping the outwardly projecting flange surrounding the door opening, a packing interposed between the projecting flange of the car door, and the parallel flange of the car, a hanger track secured to said car wall above the door opening, means for slidably mounting the door on said track, and means for moving the door laterally to either compress or release the packing between the flange of the door and the flange of the car.

2. A box car door adapted to fit in a car door opening comprising a rear wall plate and integral edge plates, an angled flange plate one member whereof fits over the edge plates the other constituting a rest for a front plate, and said front plate comprising a member projecting beyond the edge plates, and having fitted to the projecting border an agle iron, a packing fitted to said angle iron, in combination with an angle iron surrounding the door opening, a hanger track above the door opening, and a support for the door on said track permitting the door to close against said packing.

3. A box car door fashioned to move into and out of its opening; oscillatory crank hangers adjacent opposite edges of the front door plate; bearings on the outer surface of the front door plate adjacent the upper edge for said hangers; a crank at the lower end of each hanger; the door plate having slots adjacent to and below said bearings through which said cranks project; a double bell crank lever pivoted to the rear of the door plate; links to the rear of said plate extending transversely of the door plate and con nected respectively to the arms of the lever and the projecting ends of the cranks; and an operating lever upon the outside wall of the casing for moving said bell crank lever about its pivot, as and for the purpose described, and an inner wall for the door constituting an inclosing casing for said operating parts upon the inner side of the door plate.

4. A box car door fashioned to move into and out of its opening; oscillatory crank hangers adjacent opposite edges of the front door plate; bearings on the outer surface of the front door plate adjacent the upper edge for said hangers; a crank at the lower end of each hanger; the door plate having slots adjacent to and below said bearings through which said cranks project; a double bell crank lever pivoted to the rear of the door plate; links to the rear of said plate extending transversely of the door plate and connected respectively to the arms of the lever
